Timeline in success plans

I think it would be super useful to have a similar things on success plans - specifically, the ability to post updates to a "success plan" Timeline (maybe replacing / adding to the current "collaboration" tab, so CSMs can post updates on an overall success plans and not just on specific objectives as part of a success plan!

We need this capability too! We need to be able to post to the timeline from the Success Plan (could replace the collaboration tab), and then only have that success plan's timeline entries show in that tab (vs all timeline entries for the relationship). And I'm specifically referring to success plans related to the R360, not the C360.
